If you want something like this, do you really have to inherit from Enum?
To answer your question:
Somewhere in the previous threads about enums a couple people had use-cases for 
an enum with extra attributes.
So, while you don't /have/ to enherit from Enum, if Enum provides the basics of what you need, and you can extend it with the extra functionality that you need, why shouldn't you? (Not a rhetorical question -- I'm happy to learn something I don't know.)
